云服务器Tomcat配置

1.下载FileZilla

这里提一下关于FileZilla的登录方法

• 主机(H)：此处填写你购买的云服务器的外网IP地址
• 用户名(U)：此处填写root
• 密码(W)：此处填写root的登录密码，就是你在安装系统时设置的密码
• 端口(P)：此处统一填写22

2.下载Tomcat

请自行到Tomcat官网下载apache-tomcat-8.5.9

3.使用FileZilla将Tomcat上传到服务器

将下载的apache-tomcat-8.5.16.tar.gz文件上传到云服务器的/usr/soft/temp文件夹下

开始配置Tomcat服务器

• 解压apache-tomcat-8.5.16.tar.gz文件至/usr/soft/tomcat文件夹下，如果没有tomcat文件夹需要自己手动创建。

tar zxvf apache-tomcat-8.5.16.tar.gz -C /usr/soft/tomcat

• 设置JDK

cd /usr/tomcat/apache-tomcat-8.5.16/bin
vi setclasspath.sh

按'i'键后进行编辑；按'esc'键退出编辑模式后再按':'键然后输入'wq'回车进行保存；

在末尾添加以下设置：

# Set Java Environment
export JAVA_HOME=/usr/java/jdk/jdk1.7.0_80
export JRE_HOME=/usr/java/jdk/jdk1.7.0_80/jre

• 配置Tomcat服务器

1. 添加用户
   在<tomcat>/conf/tomcat-users.xml中添加以下用户

  <role rolename="admin"/>
  <role rolename="manager"/>
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <user username="admin" password="admin" roles="admin,manager,manager-gui,manager-script"/>

2.配置tomcat管理器可以远程访问的权限
tomcat默认不支持远程访问管理器，默认只能在同一台机器上访问manager，所以如果想在云服务器上访问manager需要解除该限制。
打开<tomcat>/webapps/manager/META-INF/context.xml

注释掉

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />

即可。
